Foundation or Basement - Waterproofing in London, ON
When waterproofing the basement, it is important to determine whether the water source is coming from indoors or outdoors. To discover the source, try taping aluminum foil to your basement wall - moisture on the outer surface shows the problem is indoor-related, while moisture behind the foil indicates that the problem is outdoor-related.
Found their contact a few years ago. At the time they were just starting up.
Told them to try it out on my house and so they did. They did a great job and the driveway has seen no settlement...
